1967年Ashbough等,报导了12例休克或外伤后继发了严重的呼吸衰竭,而这组患者从无肺部疾病的既往病症。其临床特点有呼吸困难、呼吸频率快,给氧也难以纠正的发绀,肺X线特点有弥漫性肺部浸润,肺顺应性降低。死亡病例的肺改变:有肺淤血、实变、肺的重量增加、并见有透明膜变。上述的病理变化与新生儿的特发性呼吸窘迫综合征(Idiopa-thic respiratory distress Syndrome)极为相似,因此命名为成人呼吸窘迫综合征(A-dult respiratory distresssyndrome(简称AR-DS)。此后文献中又以休克肺、Shock Lung Ashbough et al., 1967, reported severe respiratory failure secondary to shock or trauma in 12 patients without previous disease of lung disease. The clinical features of dyspnea, fast breathing, oxygen is also difficult to correct cyanosis, lung X-ray features diffuse pulmonary infiltrates, decreased lung compliance. Lung changes in deaths: lung congestion, consolidation, increased lung weight, and see a transparent membrane change. The pathological changes described above are very similar to the neonatal Idiopa-thic respiratory distress syndrome and are therefore named as A-dult respiratory distress syndrome (AR-DS).
